Is the sum of two binominals is always a binomial? Why or why not?

Answers

Answer:

No

Step-by-step explanation:

Algebraic Terms:

1. Monomial - an algebraic term

2. Binomial - the sum of 2 algebraic terms

3. Trinomial - an algebraic sum in 3 terms

4. Polynomial - a function in more than 1 algebraic term

The sum of 2 binomials is not always a binomial because each of the two binomials might have different algebraic terms.

If the first binomial has 2 algebraic terms and the second binomial has 2 other algebraic terms and no single term crosses out its coefficients, the sum of both binomials will not be a binomial.

A refrigerator sells for $1201. If the sales tax rate is 6.8%, what is the total price that you would pay for the fridge?

Answers

The answer is $1282.66

Explanation:

The sales tax rate (in this case 6.8%) is paid as part of selling a product. Also, to find the final price of a product, find the tax rate (percentage) of the price of the product and add this number to the price. The process to know the final price of the fridge is shown below:

1. Determine the 6.8% of $1201

 1.1. Write the values

1201  = 100  

 x     =  6.8

 1.2. Cross multiply and solve the equation

x100 = 8166

x= 8166 ÷ 100

x = 81.66

2. Add this value to the original price

$1201 + $ 81.66 = $1282.66 (Total price including the sales tax)

The sum of 6 consecutive integers is 339.

Answers

Answer:

54, 55, 56, 57, 58, and 59 are the numbers

Step-by-step explanation:

Let's pretend that the first number is [tex]n[/tex].

We know that these numbers are consecutive, meaning each number is one more than the other.

This means that

[tex]n + (n+1)+ (n+2)+ (n+3)+ (n+4)+ (n+5) = 339[/tex], since each number is consecutive.

We can combine like terms to get [tex]6n + 15 = 339[/tex].

Now let's solve for n.

[tex]6n + 15 - 15 = 339-15\\\\6n = 324\\\\n = 54[/tex]

So [tex]n=54[/tex]. This means the other 5 digits will be one more than the next.

So 54, 55, 56, 57, 58, and 59.

In each problem 7 through 14, verify that each given function is a solution of the differential equation. Y" - y = 0; y1(t) = et, y2(t) = cosh t.

Answers

Answer:

Since L.H.S = R.H.S = 0, for both [tex]y_{1} (t) = e^{t}[/tex] and [tex]y_{2} (t) = cosh(t)[/tex], y₁ and y₂ both satisfy the equation y" - y = 0 and are thus solutions to the differential equation.

Step-by-step explanation:

To check whether the given functions are solutions the given differential equation, we differentiate the functions and then insert it into the given equation.

So y" - y = 0 and  

[tex]y_{1} (t) = e^{t}\\y_{1}' (t) = e^{t}\\ y_{1}" (t) = e^{t}[/tex]

Substituting these values of y and y" into the left hand side of the equation, we have

y" - y  

[tex]y_{1}" (t) - y_{1} (t) = e^{t} - e^{t} = 0[/tex]

Since L.H.S = R.H.S

So [tex]y_{1} (t) = e^{t}[/tex] is a solution of the differential equation.

When

[tex]y_{2} (t) = cosh(t)\\ y_{2}'(t) = sinh(t) \\y_{2}"(t) = cosh(t)[/tex]

Substituting y and y" into the left hand side of the equation, we have

y" - y

[tex]y_{2}"(t) - y_{2} (t) = cosh(t) - cosh(t) = 0[/tex]

Since L.H.S = R.H.S

So, [tex]y_{2} (t) = cosh(t)[/tex] is a solution of the differential equation.

Identify the property of equality that makes Equation 1 and Equation 2 equivalent.
Equation 1
4.2x – 1.5 = 1.7x + 8.3
Equation 2
42x - 15 = 17x + 83

Answers

multiplicative property if equality. explanation: you’re just multiplying by 10.

We use the multiplicative property of equality to make Equation 1 and Equation 2 equivalent.

Given,

Equation 1 - 4.2x – 1.5 = 1.7x + 8.3

Equation 2 - 42x - 15 = 17x + 83

We have to Identify the property of equality that makes Equation 1 and Equation 2 equivalent.

We have,

Equation 1 - 4.2x – 1.5 = 1.7x + 8.3

Equation 2 - 42x - 15 = 17x + 83

If we multiply 10 on both sides of the equation, we get

10 (4.2x – 1.5)  = 10 (1.7x + 8.3)

10 x 4.2x - 10 x 1.5 = 10 x 1.7x + 10 x 8.3

42x - 15 = 17x + 8.3

We get,

42x - 15 = 17x + 8.3 which is equivalent to equation 2.

This property is called the multiplicative property of equality.

Thus we use the multiplicative property of equality to make Equation 1 and Equation 2 equivalent.

What is the point-slope form given the following slope and a point on the line? m = 3/7 , (7, -4)

Answers

Answer:

The equation is y = (3/7)x - 7.

Step-by-step explanation:

Given that the point slope form of an equation is y = mx + b where m represents the gradient and b is the y-intercept. Then, you have to substitute the following values into the equation :

[tex]y = mx + b[/tex]

[tex]let \: m = \frac{3}{7} ,x = 7,y = - 4[/tex]

[tex] - 4 = \frac{3}{7} (7) + b[/tex]

[tex] - 4 = 3 + b[/tex]

Timothy has three friends. The following table shows the distance and time it takes him to drive to each of his friends’ houses. 5 km 11 km 18 km to 10 min 15 min 20 min. Is the time it takes Timothy to drive to his friends’ houses proportional to the distance

Answers

Answer:

No

Step-by-step explanation:

The time it takes Timothy to drive to his friends' houses is not proportional. This is because when going to the first house, he is going at 4km per minute, but when visiting the second and third houses he is no longer traveling at that speed.

In a directly proportional relationship, increasing one variable will increase another. The given relationship is not proportional.

What is the directly proportional and inversely proportional relationship?

In a directly proportional relationship, increasing one variable will increase another.

This directly proportional relationship between p and q is written as

p∝q where that middle sign is the sign of proportionality.

Inversely proportional relationship increasing one variable will decrease the other variable if both are inversely proportional.

This directly proportional relationship between p and q is written as

p∝1/q where that middle sign is the sign of proportionality.

Given that the table shows the distance and time it takes him to drive to each of his friends’ houses.

Now, to know if the time it takes Timothy to drive to his friends’ houses proportional to the distance, find the ratio of distance to time for each row. Therefore, the ratios can be written as,

R₁ = 5km / 10 min = 0.5 km per min

R₂ = 11 km / 15 min = 0.7334 km per min

R₃ = 18 km / 20 min = 0.9 km per min

Since the ratio of distance and time in different cases is different, therefore, the given relationship is not proportional.

A scientist creates a colony of bacteria in a dish. This type of
bacteria duplicates itself per minute.
If at 9am the experiment started with a single cell and at 9:13
the dish was half-full, at what time will the dish be full?

Answers

Answer: 9:14

Step-by-step explanation: So if he started if 1 bacteria, it becomes 2 bacteria at 9:01, etc. So at 9:13, it is 2^13 and if that is half, that means 2^14 is when it is full so 9:14.

The dish will be full at  9:14 am.

Given, the bacteria duplicates itself per minute.

The experiment started with a single cell at 9 am and at 9:13 am the dish was half full.

So it is clear that after 13 minutes of experiment started the dish was half full.

Now, let here is only 1 bacteria in the dish which is duplicating per minute,so after 1 minute it becomes 2 after that it becomes 4 and after that it becomes 8. Hence it is clear from the example the bacteria doubles itself in powers of her minute. ([tex]2^x[/tex])  here x is the number of minute.

Since after 13 minutes the dish was half full, it means there are [tex]2^{13}[/tex] bacteria in the dish. hence the full dish is [tex]2^{14}[/tex] bacteria. so the bacteria will take 1 more minute for the dish to be full.

Hence at 9:14 am the dish was full.

What are Arithmetic operations?

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.

+ Addition operation: Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

For example 4 -2 = 2

A drone takes off from the base of a mountain at a height of 27 ft below sea level.

To determine the height of the mountain.

Using the arithmetic operations of addition and subtraction,

The drone then flies up 642 ft before landing at the top of the mountain.

Assume that distance below sea level is positive,

So the height of the mountain as

⇒ 642 + 27
